The default setting is to disable compression. Traffic shaping Traffic can be shaped by establishing a rate limit per tunnel. A committed rate guarantees a fixed amount of bandwidth and is assigned to a tunnel. The committed rate setting ensures that an FCIP tunnel operates at the specific fixed rate for FCIP traffic. The rest of the possible 1000 Mbps rate that a GE interface provides is available to other tunnels created on this GE interface. If the committed rate is too small for the amount of FCIP traffic, the FCIP tunnel is limited to that rate and performance may be affected. Total bandwidth of all committed and uncommitted rate tunnels must not exceed 1000 Mbps. When allocating committed rates to tunnels, do not allocate more bandwidth than the WAN can support or your FCIP tunnel may not be stable. Fabric OS FCIP Administrator's Guide 43 53-1001766-01
